Embodiment Construction

[0044] As shown in FIG. 1, a light source locating and visualization apparatus 10 of this present invention is an apparatus used to locate superficial veins or specific structures with a light source including LED, Xenon lamp bulb or tungsten lamp bulb, but preferably using a red LED as a light source. Said apparatus 10 is applicable to injection, intravenous injection, blood vessel searching and identification of the boundary between different superficial structures, and is capable to show the size, curve, and bifurcation of subcutaneous blood vessels in a real-time manner as shown in FIGS. 5 and 9, facilitating physicians and nurse by naked eyes to visually select appropriate position on a blood vessel for intravenous injection.

[0045] As shown in FIG. 1, an indented insertion groove 11, preferably shaped in indented U-sectional groove, V-sectional groove or the like, is disposed on the top of the light source locating and visualization apparatus 10 of this present invention.

Abstract

A light source locating and visualization apparatus comprises one or more than one LEDs capable to radiate a red light source with a wavelength of 600˜650 nm to locate superficial veins or specific structures; and a method of locating superficial veins with a LED light source comprises to proceed a skin-tightly radiating by using the source locating and visualization apparatus to emitting a red LED light source with wavelength of 600˜656 nm; to produce a lateral scattering and illumination effect by way of emitting red LED light source penetrating through a fat structure to cause reflection and scattering; and to locate superficial veins by naked eyes due to said superficial veins capable of absorbing red light spectrum easily and appearing as a located blood vessel shadow under the lateral scattering and illumination effect; therefore, physicians and nurse are capable by naked eyes to see the size, curve, and bifurcation of subcutaneous blood vessels visually and then select an appropriate injection position along the blood vessel for intravenous puncture easily.
